You can lift up on the locking tab on the side where you see the wires going into the coil and this will stop the spark plugs from firing in that particular cylinder giving you misfire codes AKA replace injector codes. Do this while the engine is running 1 at a time on as many cylinders as you can. You will have enough codes to get all injectors replaced.

it is too late that i found this trick to surprise the dealer
the problem came after the warranty was over
so there is no forum member pay on their own, to replacing the fuel injectors?
